"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.
Netflix has dropped out of the bidding war for Warner Bros. Discovery (WBD), making Paramount Skydance the expected owner of WBD. A Paramount-WBD merger remains subject to regulatory approval, but it’s likely that we will see a Paramount-Skydance-Warner-Bros.-Discovery media giant.

Instagram is adding a new alert for the parents of teen users of its social media platform. The network will alert the adult if their child repeatedly searches for terms about suicide or self-harm in a short time frame. From that notification, the parent will optionally be able to access resources for having conversations with their teen about these topics. These alerts will begin rolling out for parental supervision users in the US, UK, Australia and Canada next week, with later regions to be added in the future.。关于这个话题,safew官方版本下载提供了深入分析
